Lazy virtual filesystem instantiation and caching
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11914556) developed by Ignatowicz; Eder, Cambridge, MA, and Bakos; Alexandre Porcelli, Westford, MA, for “lazy virtual filesystem instantiation and caching.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A host with a memory, which stores a guest, a filesystem cache, and a proxy cache, has a filesystem manager executing on a processor that receives a first request to locate a file in a first filesystem. In response to receiving the first request, a filesystem proxy in the proxy cache associated with the first filesystem is queried. The first request is responded to based on metadata retrieved from the filesystem proxy. A second request is received to modify the file. In response to receiving the second request, the first filesystem is instantiated in the filesystem cache, where a second filesystem is evicted from the filesystem cache to reclaim storage capacity for the first filesystem. The file in the first filesystem is modified.”

The patent application was filed on 2018-10-19 (16/165475).

Writeback overhead reduction for workloads
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11914512) developed by Tsirkin; Michael, RaAnana, Israel, Arcangeli; Andrea, New York, NY, and Scrivano; Giuseppe, Milan, Italy, for a “writeback overhead reduction for workloads.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An example system includes a memory, a processor in communication with the memory, and a supervisor. The supervisor is configured to allocate a memory space in the memory to a workload executing on the processor. The supervisor is configured to store data written by the workload as dirty memory in the memory space at least until the data is written back to a data storage. Based on a type of the workload being a first type, the supervisor is configured to trigger write back of at least a portion of the dirty memory into the data storage in response to the dirty memory exceeding a threshold level. Based on the type of the workload being a second type, the supervisor is configured to delay write back of the dirty memory into the data storage in response to the dirty memory exceeding the threshold level.”

Overlay container storage driver for microservice workloads
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11893407) developed by Deutsch; Fabian, Grasbrunn, Germany, Litke; Adam Gerard, Harrisburg, PA, and Chen; Huamin, Westford, MA, for an “overlay container storage driver for microservice workloads.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A first command is received from a workload, by a host system executing a nested container storage interface (CSI) driver, to create a persistent volume. The nested CSI driver converts the first command used by the workload to create the persistent volume to a second command used by the host system to increase a capacity of a previously generated persistent volume allocated to the workload. The second command is transmitted to an undercluster CSI driver of the host system, wherein the second command causes the undercluster CSI driver to increase the capacity of the previously generated persistent volume.”

The patent application was filed on 2020-09-24 (17/030747).

Prefetching data in distributed storage system
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11860788) developed by BenHanokh; Gabriel Zvi, Tel-Aviv, Israel, and Salomon; Yehoshua, Kfar Saba, Israel, for “prefetching data in a distributed storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Data can be prefetched in a distributed storage system. For example, a computing device can receive a message with metadata associated with at least one request for an input/output operation from a message queue. The computing device can determine, based on the message from the message queue, an additional IO operation predicted to be requested by a client subsequent to the at least one request for the IO operation. The computing device can send a notification to a storage node of a plurality of storage nodes associated with the additional IO operation for prefetching data of the additional IO operation prior to the client requesting the additional IO operation.”
